[jira] [Created] (IOTDB-1581) Consider deletions when recovering
tsFileResource of incomplete tsfile
Minghui Liu created IOTDB-1581:
----------------------------------
Summary: Consider deletions when recovering tsFileResource of incomplete tsfile
Key: IOTDB-1581
URL: https://issues.apache.org/jira/browse/IOTDB-1581
Project: Apache IoTDB
Issue Type: Bug
Reporter: Minghui Liu
When recovering a incomplete TsFile:
* Call `recoverResourceFromWriter` to recover the resource information through the ChunkMetadata information in `RestorableTsFileIOWriter`
* Call the `redoLogs` method to write the data in one or more wal files corresponding to this file to a temporary Memtable and persist to this incomplete TsFile
The deletions ( Recorded in the .mods file ) are not considered in the two aspects, resulting in the recovery time range being wider than actual.
